Cell user occupancy indicator to enhance intelligent traffic steering

ABSTRACT

Traffic associated with user equipment that are served by a first radio access network is steered to a second radio access network based on a cell user occupancy criterion. Cell user occupancy data that represents a maximum number of devices served by an access point is determined based on a type of the access point (e.g., macro access point, femto access point, WiFi access point, etc.). Further, based on the cell user occupancy data, a normalized index value is generated that is relative to different cell types/capacities. The cell user occupancy data is then transmitted to one or more neighboring access points that can utilize the cell user occupancy data to facilitate traffic steering, load balancing, and/or neighbor relationship management.

TECHNICAL FIELD

The subject disclosure relates to wireless communications, e.g., to a cell user occupancy indicator that enhances intelligent traffic steering.

BACKGROUND

With an explosive growth in utilization of communication devices, mobile telecommunications carriers are seeing an exponential increase in network traffic. To meet the demands of higher traffic, conventional systems employ traffic steering mechanisms that offload mobile traffic from a first cell to an overlapping second cell. For example, if the first cell is determined to be congested, one or more data flows of a user equipment coupled to a first access point of the first cell can be steered to a second access point of the second cell. As more traffic is steered to the second cell, the load of the second cell increases and is driven closer to maximum load level (e.g., congested state). In a complex communication networks, for example, with multiple layers (e.g., macro cells, pico cells, femtocells, etc.) and/or multiple technologies (e.g., Long Term Evolution (LTE), Universal Mobile Telecommunications System (UMTS), WiFi, etc.), network conditions (e.g., traffic, capacity) vary throughout the day and steering traffic to a congested target cell can result in a ping-pong effect wherein the traffic is oscillated between cells.

The systems and methods disclosed herein facilitate enhancing network steering and/or load balancing decisions by utilization of cell user occupancy data associated with a cell site. As an example, the terms “traffic steering” as used herein can refer to directing, attempting to direct, and/or instructing to direct or deliver, via a first access point, at least a portion of traffic (data flows/packets) associated with a communication device that is coupled to and/or communicating via a second access point. In one aspect, a source cell site can receive information indicative of user occupancy of a target cell site and utilize the information to ascertain whether traffic from a user equipment, coupled to the source cell site, should be steered to the target cell site. For example, if determined that the target cell site has a low user occupancy (e.g., femtocell, picocell, small cells, etc.), it may not be a desirable/optimal cell to handover to. Understanding the cell user occupancy of neighboring cells can reduce congestion and result in stronger network performance.

Referring initially to FIG. 1, there illustrated is an example system 100 that facilitates a transfer of cell user occupancy data between access points in a communication network, according to one or more aspects of the disclosed subject matter. System 100 can be part of a communication network (e.g., cellular network) and can include a source access point 102 and a target access point 104. In one aspect, the source access point 102 and/or the target access point 104 can be part of a self optimizing network (SON). As an example, the access points (102, 104) can include, but are not limited to, a base station, an eNodeB, a picostation, a WiFi access point, a femto access point, a HomeNodeB (HNB), an eHNB, microcell access point, etc. In one aspect, the source access point 102 and the target access point 104 are neighboring access points such that, the coverage areas of the source access point 102 and the target access point 104 at least partially overlap to facilitate handover between the cell sites. Further, although only one target access point 104 is depicted in FIG. 1, the subject specification is not so limited and system 100 can comprise one or more target access points.

In one embodiment, target access point 104 can determine cell user occupancy data 106 associated with the target access point 104. For example, the cell user occupancy data 106 can represent a maximum capacity supported by the target access point 104, for example, based on the type of cell (e.g., macro cell, small cell, femtocell, picocell, etc.). Further, the cell user occupancy data 106 can be a composite capacity value that is computed relative to other cells. Moreover, the cell user occupancy data 106 helps select an optimal cell for traffic steering, for example, when the source access point 102 is congested or nearing congestion. The target access point 104 can transmit (e.g., periodically, on demand, in response to determining a change in the cell user occupancy, etc.) the cell user occupancy data 106 to one or more neighboring access points for example, source access point 102. In one aspect, the source access point 102 can utilize the cell user occupancy data 106 to determine whether traffic from one or more user equipment (UE), for example, UE 108, that are served by the source access point 102, is to be steered to the target access point 104. As an example, the cell user occupancy data 106 provides context to load index data (e.g., current load value) and/or congestion index data (e.g., current capacity utilization value) of the target access point 104. Moreover, the cell user occupancy data 106 is utilized by the source access point 102 to determine the amount of occupancy specific to the cell type of the target access point 104, for example, e.g., 30% capacity of a macro cell does not correlate to 30% capacity of a picocell or femtocell. In the above example scenario, the macro cell that has 30% current cell user occupancy is determined to be a more desirable/optimal cell to move traffic as compared to the smaller picocell/femtocell with 30% cell user capacity. Accordingly, if the cell user occupancy data 106 is high (e.g., above a defined threshold value), the traffic from UE 108 can be steered to the target access point 104; else, if the cell user occupancy data 106 is low (e.g., equal to or less than the defined threshold value), the traffic from UE 108 can be steered to another target access point (not shown) with a higher cell user occupancy and/or the traffic from UE 108 can continue to be communicated via the source access point 102.

In one aspect, the steering decision can be made by the source access point 102, which can instruct the UE 108 to steer the traffic to a selected (e.g., based in part on the cell user occupancy data 106) target access point. In another aspect, the source access point 102 can forward (e.g., via a set of cell broadcast messages) the cell user occupancy data 106 to the UE 108 and the UE 108 can make the steering decision based on the cell user occupancy data 106. In yet another aspect, the UE 108 and/or the source access point 102 are not limited to solely/independently making a network selection decision for traffic steering and can participate in a joint selection process with one or more devices (not shown) that are coupled to the UE 108 and/or the source access point 102 to facilitate selection of a target access point to which traffic is to be steered. Moreover, if determined (e.g., based in part on the cell user occupancy data 106) that traffic associated with the UE 108 is to be steered to the target access point 104, then the UE 108 can communicate one or more data flows via the target access point 104 (e.g., depicted by the dotted line in FIG. 1). As an example, the UE 108 can include most any electronic communication device such as, but not limited to, most any consumer electronic device, for example, a tablet computer, a digital media player, a digital photo frame, a digital camera, a cellular phone, a personal computer, a personal digital assistant (PDA), a smart phone, a laptop, a gaming system, etc. Further, UE 108 can also include, LTE-based devices, such as, but not limited to, most any home or commercial appliance that includes an LTE radio. It can be noted that UE 108 can be mobile, have limited mobility and/or be stationary. In one example, UE 108 can include a multi-band, multi-mode, and/or multi-radio device.

Referring now to FIG. 2, there illustrated is an example system 200 for determining cell user occupancy data that is employed to facilitate traffic steering, in accordance with an aspect of the subject disclosure. In one aspect, system 200 facilitates determination of cell user occupancy data associated with a target access point 104 that can be utilized by a set of neighboring access points (e.g., source access point 102) to facilitate traffic steering and/or load balancing. It is noted that the source access point 102 and the target access point 104 can include functionality as more fully described herein, for example, as described above with regard to system 100. In one example, the target access point 104 can include, but is not limited to an access point that is operated and/or deployed by a service provider of the communication network 204, and that utilizes the same or different radio technologies for communication with the UEs (e.g., UE 108) as utilized by source access point 102. Further, in another example, the source access point 102 and the target access point 104 can be deployed in the same or different (commonly owned/operated) networks (e.g., Heterogeneous networks).

According to an embodiment, the target access point 104 can include an occupancy determination component 208 that can determine cell user occupancy of the target access point 104. In one aspect, the cell user occupancy can include a pre-configured parameter, based on actual cell capability (both hardware and software) of the target access point 104. As an example, the occupancy determination component 208 can receive the pre-configured parameter from a network configuration server 202 of communication network 204 (e.g., during initialization, power-up, periodically, based on an event, on demand, etc.). In another example, the pre-configured parameter can be pre-programmed and stored in the data store 206 of the target access point, for example, by the manufacturer and/or service provider. It is noted that the data store 206 can include volatile memory(s) or nonvolatile memory(s), or can include both volatile and nonvolatile memory(s). Examples of suitable types of volatile and non-volatile memory are described below with reference to FIG. 14. The memory (e.g., data stores, databases) of the subject systems and methods is intended to comprise, without being limited to, these and any other suitable types of memory.

In one aspect, the cell user occupancy can represent a maximum number of user equipment that can simultaneously (or substantially simultaneously) be served by and/or coupled to (e.g., via an air interface) the target access point 104. A classification of the access point (e.g., a macro access point, a femto access point, a pico station, etc.) can be employed to determine the cell user occupancy. For example, since a macro cell can serve a greater number of user equipment than that served by a femtocell/picocell, a macro cell can be assigned (e.g., by the occupancy determination component 208) a greater cell user occupancy than that of the femtocell/picocell.

In one aspect, the occupancy determination component 208 can normalize the cell user occupancy value relative to different cell types. For example, an index number “2” can be assigned to the cell user occupancy to if the target access point 104 is determined (e.g., by the occupancy determination component 208) to be a femtocell that supports a maximum of four user equipment; an index “4” can be assigned to the cell user occupancy to if the target access point 104 is determined (e.g., by the occupancy determination component 208) to be a picocell that supports a maximum of sixteen user equipment; an index “10” can be assigned to the cell user occupancy to if the target access point 104 is determined (e.g., by the occupancy determination component 208) to be a macro cell. It is noted that the cell user occupancy data is not limited to the above index values, and can comprise most any normalization and/or classification technique. For example, the occupancy determination component 208 can classify the cell user occupancy as “low,” “regular,” “high,” etc. based on predefined threshold values.

The normalized and/or classified cell user occupancy value can then be transmitted to neighboring access points (e.g., source access point 102) by the data transfer component 212, for example, based on operator-defined network policies 210. As an example, the data transfer component 212 can transmit the cell user occupancy information, via X2 interfaces enabled by SON and/or most any other transport mechanisms. Moreover, the data transfer component 212 can transmit the cell user occupancy data at various times, such as, but not limited to, periodically, on demand, based on detecting an event, based on detecting a change in a the cell user occupancy, based on determining that the cell user occupancy exceeds a defined threshold, based on receiving a query from the source access point device, during initialization, etc. In one embodiment, the cell user occupancy data can be included within or appended to a resource status update message, for example, a RIM (Radio Access Network (RAN) Information Message) that contains other information, such as (but not limited to) current network load, current user capacity (e.g., number of devices currently being served) of the target access point 104. Alternatively, the cell user occupancy data can be transmitted as a new/separate message. The source access point 102 can utilize the cell user occupancy data to enhance traffic steering decisions. In an alternate embodiment, the occupancy determination component 208 can determine an absolute value of cell user occupancy (e.g., 5 user, 10 users, 50 users, etc.), the data transfer component 212 can transmit the absolute value to the source access point 102, and the source access point can normalize (and/or classify) the received the absolute value.

Referring now to FIG. 3, there illustrated is an example system 300 that utilizes cell user occupancy data of target access points to facilitate efficient network selection, according to an aspect of the subject disclosure. It is noted that the source access point 102, communication network 204, and the network policies 210 can include functionality as more fully described herein, for example, as described above with regard to systems 100 and 200. Further, target access points 104 ₁-104 _(n) (where n is a positive integer) are substantially similar to target access point 104 and can include functionality as more fully described herein, for example, as described above with regard to target access point 104.

In one aspect, a data reception component 302 can receive the cell user occupancy data transmitted by one or more neighboring access point devices, including, the target access points 104 ₁-104 _(n) (e.g., via a RIM). Additionally or optionally, the data reception component 302 can also receive respective current capacity information (e.g., number of UE that are currently coupled to the neighboring access points) of the one or more neighboring access points. As an example, the data reception component 302 can parse the received message(s) and provide the respective cell user occupancy data to a traffic steering component 304 and/or a neighbor management component 306. The traffic steering component 304 analyzes the cell user occupancy data to select a target access point from the target access points 104 ₁-104 _(n), to which traffic from a UE coupled to the source access point 102 should be steered to (e.g., if the load of the source access point 102 has increased above a threshold value). In one aspect, the data reception component 302 can receive normalized values (and/or classifications) for the cell user occupancy of the target access points 104 ₁-104 _(n). In another aspect, the data reception component 302 can receive absolute values (and/or classifications) for the cell user occupancy of the target access points 104 ₁-104 _(n) and can normalize and/or classify the received values relative to each other and/or based on predefined thresholds.

According to an embodiment, the traffic steering component 304 can determine whether the cell user occupancy data satisfies a predefined criterion (e.g., set based on the network policies 210). For example, the traffic steering component 304 can compare the cell user occupancy index values received from the target access points 104 ₁-104 _(n) and select the target access points having the highest cell user occupancy index values. In another example, the traffic steering component 304 can compare the cell user occupancy index value of a particular access point of the target access points 104 ₁-104 _(n) to a threshold value and/or range. If the cell user occupancy index value is higher than the threshold value (and/or within the range), the traffic steering component 304 can instruct one or more UEs (e.g., UE 108), coupled to the source access point 102 to connect to the selected target access point and steer at least a portion of their traffic via the selected target access point. It is noted that the UEs are not limited to communicating all data (e.g., IP flows) through the new access point and that the UEs can select a first portion of data (e.g., select a first set of IP flows) that can be communicated via the selected target access point and a second portion of data (e.g., select a second set of IP flows) that can be communicated via the source access point 102. As an example, the selection of the data (e.g., IP flows) can be based on network policies 210, e.g., using an access network discovery and selection function (ANDSF). Alternatively, if the cell user occupancy index value is lower than the threshold value (and/or outside the range), the traffic steering component 304 can determine that the specific target access point is not an optimal candidate for traffic steering and can select another access point (from the target access points 104 ₁-104 _(n)) via which the UEs can communicate and/or can instruct the UEs to continue communicating via the source access point 102.

In addition to the cell user occupancy data, the traffic steering component 304 can utilize the current cell user capacity data of the target access points 104 ₁-104 _(n) to further enhance the network selection and/or traffic steering decision. Moreover, the traffic steering component 304 can bias mobility parameters based on the current user capacity condition and the cell user occupancy. A weighting on the cell user occupancy can be dynamically and/or automatically adjusted based on current user capacity and/or current load. As an example, the target access point (e.g., target access point 1 104 ₁) that has a low maximum user occupancy, that is at 70% load is ranked lower (e.g., by the traffic steering component 304) than another target access point (e.g., target access point 2 104 ₂) a cell that has a high maximum user capacity with 70% load. Accordingly, in this example, the traffic steering component 304 can assign a higher bias to mobility parameters of target access point 2 104 ₂ than the bias assigned to mobility parameters of target access point 1 104 ₁. Moreover, the cell user occupancy data normalizes an index to encompass different cells (e.g., macro, femto, pico etc. . . . ) and different functionality/implementation that can impact maximum user occupancy and facilitated steering of traffic in an intelligent manner between the different cells (e.g., multi technology/vendor/layer).

Although depicted as completely residing within the source access point 102, it can be noted that the traffic steering component 304 can be distributed among multiple devices, such as, but not limited to, a network device and/or a UE (not shown) served by the source access point 102. For example, the network device can determine the biased mobility parameters (e.g., based on the cell user occupancy data) and the source access point 102 can simply forward the mobility parameters and/or instructions to steer traffic, to the UEs coupled to the source access point 102. Alternatively, the source access point 102 can simply forward (e.g., via a cell broadcast message) the cell user occupancy data (and the current cell user capacity) received from the target access points 104 ₁-104 _(n) to the UEs, which in turn can analyze the information to determine and/or bias mobility parameters and select a radio access network via which traffic is to be communicated.

In one embodiment, the cell user occupancy data can also be utilized by a neighbor management component 306 that manages neighbor relations to dynamically prioritize/rank neighbor cell sites based on their respective cell user occupancy data. Moreover, the neighbor management component 306 can update a Neighbor Relation Table (NRT) (not shown). In one aspect, based on the cell user occupancy data, identifier data representing the target access points 104 ₁-104 _(n) can be added to, deleted from, and/or ranked higher/lower, in the table. For example, if the cell user occupancy of the target access point 1 104 ₁ has increased, the ranking of the target access point 1 104 ₁ can be increased (and/or vice versa) and/or the data representing the target access point 1 104 ₁ can be added to the NRT.

Referring now to FIG. 4, there illustrated is an example system 400 that facilitates query-based traffic steering, according to one or more aspects of the disclosed subject matter. It can be noted that the source access point 102, the target access point 104, and UE 108 can include functionality as more fully described herein, for example, as described above with regard to systems 100-300.

In one aspect, the target access point 104 can determine (e.g., by employing the occupancy determination component 208) cell user occupancy data associated with the target access point 104 that is indicative of a normalized value (relative to different cell types) representing a maximum number of devices that can be served by the target access point at a given time. Further, the target access point 104 can transmit (e.g., by employing the data transfer component 212) the cell user occupancy data to a network load management system 402 of the communication network. It can be noted that the network load management system 402 can be locally coupled to the source access point 102 and/or the target access point 104, for example, located within the radio access network (RAN) (e.g., be part of the SON) or can be located elsewhere within the communication network. Moreover, the network load management system 402 can store data received from one or more access points, including target access point 104, in a load condition(s) data store 404. This stored data can be accessed by the source access point 102, for example, if the source access point 102 does not directly receive the cell user occupancy data from the target access point 104. It can be noted that the network load management system 402 can collect the cell user occupancy data in a pull configuration with the one or more access points (e.g., target access point 104) and/or receive the cell user occupancy data pushed by one or more access points (e.g., target access point 104).

According to an aspect, the source access point 102 (and/or UE 108) can initiate a query for the cell user occupancy data. As an example, the query can be transmitted periodically (e.g., based on predefined timing intervals), on-demand, in response to an event, etc. In response to receiving the query, the network load management system 402 can identify access points that are neighboring the source access point 102 (including target access point 104), lookup load condition data (e.g., cell user occupancy data) received from the neighboring access points in the load condition(s) data store 404, and transmit the data to the source access point 102 (and/or UE 108).

In an aspect, the query generated by the source access point 102 (and/or UE 108) can include data such as (but not limited to) the served physical cell ID (PCI) of the source access point 102, the cell identifier (ID) associated with the source access point 102, the Basic Service Set IDentifier (BSSID) and/or the Service Set Identifier (SSID) (if the RAN includes or is otherwise capable of receiving load information from a nearby a WiFi network). Based on the PCI/SSID/BSSID, the network load management system 402 can identify the network sectors corresponding to the source access point 102 and/or the one or more neighboring access points (e.g., target access point 104), dynamically determine (and/or lookup) the corresponding network load information (e.g., cell user occupancy data), and transmit the determined information to the source access point 102 (and/or UE 108). The source access point 102 (and/or UE 108) can receive the cell user occupancy data (e.g., via the data reception component 302) and analyze the cell user occupancy data to facilitate traffic steering and/or update mobility parameters.

FIG. 5 illustrates an example flow diagram 500 that depicts a transfer of cell user occupancy data between access points in an LTE network. In this example scenario, source access point 102 and target access point 104 are part of a SON in an LTE communication network. It can be noted that the source access point 102 and the target access point 104 can include functionality as more fully described herein, for example, as described above with regard to systems 100-400. As an example, the source access point 102 and the target access point 104 can communicate via an X2 Application Protocol (X2AP) to exchange load measurement data. At 502, the source access point 102 can transmit a Resource Status Request to the target access point 104 to initiate transfer of load measurement data from the target access point 104. In one aspect, the Resource Status Request can request for the cell user occupancy data of the target access point 104. As an example, a cell user occupancy indicator can be included as a bit (e.g., sixth bit) in a bitmap provided in the request. In addition, the Resource Status Request can request various other load measurements, such as, but not limited to, current load, bandwidth utilization, number of UEs currently coupled to the target access point 104, etc. On receiving the Resource Status Request, the target access point 104 can perform requested load measurement data based on the parameters specified in the Resource Status Request and/or determine (e.g., lookup) saved measurement data from data store 206.

At 504, the target access point 104 can then transmit a Resource Status Response indicative of a set of the requested load measurements that are available (e.g., results are available, measurements can be performed, etc.) and that can be provided to the source access point 102. If none of the measurements are available, the resource status response can be indicative of a failure message. Further, at 506, a Resource Status Update is transmitted from the target access point 104 to the source access point 102 with the available load measurements (e.g., including the cell user occupancy indicator). As an example, the source access point 102 can utilize the load measurements to facilitate load balancing and/or intelligent traffic steering.

FIG. 6 illustrates an example flow diagram 600 that depicts a transfer of cell user occupancy data from a UMTS network to an LTE network. In this example scenario, source access point 102 is an eNB in an LTE communication network, while the target access point 104 (not shown) is an access point (e.g., base station, HNB, etc.) within a UMTS network. It can be noted that the source access point 102 can include functionality as more fully described herein, for example, as described above with regard to systems 100-400. As an example, the UMTS network can comprise a mobility management entity (MME) 602, a serving GPRS support node (SGSN) 604 and a radio network controller (RNC) 606. In one aspect, at 608, the source access point 102 can transmit an eNB Direct Information Transfer message to the MME 602 to request for load measurements (e.g., including cell user occupancy data) from neighboring cell sites (e.g., including target access point 104). At 610, the MME 602 can forward the request to the SGSN 604 via a RAN Information Relay message and at 612, the SGSN 604 can forward the request to the RNC 606 via a Direct Information Transfer message. The RNC is coupled to the target access point 104 and can request and receive, from the target access point 104, load measurement data, including, but not limited to, cell user occupancy data associated with the target access point 104. At 614, the RNC 606 can encapsulate the load measurement data in a Direct Information Transfer message that can be sent to the SGSN 604. At 616, the SGSN 604 can transfer the load measurement data to the MME 602 via a RAN Information Relay message and at 618, the MME 602 can forward the load measurement data to the source access point 102 via an MME Direct Information Transfer message. As an example, the source access point 102 can utilize the load measurements to facilitate load balancing and/or intelligent traffic steering.

FIG. 7 illustrates an example flow diagram 700 that depicts a transfer of cell user occupancy data from an LTE network to a UMTS network. In this example scenario, target access point 104 is an access point (e.g., eNB) in an LTE communication network, while the source access point 102 (not shown) is an access point (e.g., base station, HNB, etc.) within a UMTS network. It can be noted that the target access point 104, MME 602, SGSN 604, and RNC 606 can include functionality as more fully described herein, for example, as described above with regard to systems 100-600. In one aspect, the RNC 606 can be coupled to and can control the source access point 102 (not shown), which can request for load measurements from neighboring cell sites (e.g., including target access point 104) via the RNC 606. At 702, the RNC 606 can transmit a Direct Information Transfer message to the SGSN 604 to request for the load measurement data (e.g., including cell user occupancy data). At 704, the SGSN 604 can forward the request to the MME 602 via a RAN Information Relay message and at 706, the MME 602 can forward the request to the RNC 606 via an MME Direct Information Transfer message. On receiving the MME Direct Information Transfer message, the target access point 104 can perform requested load measurements based on the parameters specified in the Direct Information Transfer message and/or determine (e.g., lookup) saved measurement data from data store 206.

At 708, the target access point 104 can transmit the load measurement data (e.g., including cell user occupancy data) to the MME 602. At 710, the MME 602 can forward the load measurement data to the SGSN 604 via a RAN Information Relay message and at 712, the SGSN 604 can transfer the load measurement data to the RNC 606 via a Direct Information Transfer message. The RNC 606 can then transfer the load measurement data to the target access point 104, which can utilize the cell user occupancy data to facilitate load balancing and/or intelligent traffic steering. It is noted that the subject specification is not limited to communication messages (e.g., X2AP: Resource Status Request, X2AP: Resource Status Response, X2AP: Resource Status Update, eNB Direct Information Transfer, RAN Information Relay, Direct Information Transfer, and MME Direct Information Transfer) depicted in FIGS. 5-7 and that most any communication messaging protocols can be utilized to transfer the cell user occupancy data between access points. Further, it can be noted that although described herein as a cellular access point, the target access point 104 can also be an access point associated with a wireless local area network, WiFi access point, etc.

Referring now to FIG. 8, there illustrated is an example system 800 that employs one or more artificial intelligence (AI) components (802 ₁, 802 ₂), which facilitate automating one or more features in accordance with the subject embodiments. It can be appreciated that the source access point 102, the target access point 104, the occupancy determination component 208, the data transfer component 212, the data reception component 302, the traffic steering component 304 and the neighbor management component 306 can include respective functionality, as more fully described herein, for example, with regard to systems 100-700.

In an example embodiment, system 800 (e.g., in connection with automatically determining data transfer parameters, traffic steering criteria, a bias for mobility parameters, neighbor relationships, etc.) can employ various AI-based schemes for carrying out various aspects thereof. For example, a process for determining an optimal time/schedule to transfer the cell user occupancy data, etc. can be facilitated via an automatic classifier system implemented by AI component 802 ₁. Additionally or alternatively, a process for determining whether UEs are to be steered to the target access point 104 to efficiently reduce network congestion at the source access point 102 without negatively impacting user experience, determining which RAN network is to be selected, determining when a query for load measurement data is to be transmitted, etc. can be facilitated via an automatic classifier system implemented by AI component 802 ₂.

A classifier can be a function that maps an input attribute vector, x=(x1, x2, x3, x4, xn), to a confidence that the input belongs to a class, that is, f(x)=confidence(class). Such classification can employ a probabilistic and/or statistical-based analysis (e.g., factoring into the analysis utilities and costs) to prognose or infer an action that a user desires to be automatically performed. In the case of communication systems, for example, attributes can be information received from UEs and/or access points, and the classes can be categories or areas of interest (e.g., levels of priorities). A support vector machine (SVM) is an example of a classifier that can be employed. The SVM operates by finding a hypersurface in the space of possible inputs, which the hypersurface attempts to split the triggering criteria from the non-triggering events. Intuitively, this makes the classification correct for testing data that is near, but not identical to training data. Other directed and undirected model classification approaches include, e.g., naïve Bayes, Bayesian networks, decision trees, neural networks, fuzzy logic models, and probabilistic classification models providing different patterns of independence can be employed. Classification as used herein can also be inclusive of statistical regression that is utilized to develop models of priority.

As will be readily appreciated from the subject specification, an example embodiment can employ classifiers that are explicitly trained (e.g., via a generic training data) as well as implicitly trained (e.g., via observing access point/UE behavior, user/operator preferences, historical information, receiving extrinsic information, network load/congestion trends, type of UE, type of target RAN, etc.). For example, SVMs can be configured via a learning or training phase within a classifier constructor and feature selection module. Thus, the classifier(s) of AI component 802 ₁ can be used to automatically learn and perform a number of functions, including but not limited to determining according to a predetermined criteria when and/or or to which devices is the cell user occupancy data to be transmitted, a schedule according to which the cell user occupancy is to be monitored, the time interval utilized to calculate the cell user occupancy, etc. Further, the classifier(s) of AI component 802 ₂ can be used to automatically learn and perform a number of functions, including but not limited to determining according to a predetermined criteria a RAN to which the UEs coupled to source access point 102 are to be handed over, a bias assigned to a mobility parameter, a triggering threshold, a time at which a query for cell user occupancy data is to be transmitted (e.g., to target access point 104), etc. The criteria can include, but is not limited to, historical patterns and/or trends, user preferences, service provider preferences and/or policies, location of the access point, current time, type of target RAN (e.g., macro cell, femtocell, WiFi network, etc.), network load, and the like.

FIGS. 9-11 illustrate flow diagrams and/or methods in accordance with the disclosed subject matter. For simplicity of explanation, the flow diagrams and/or methods are depicted and described as a series of acts. It is to be understood and appreciated that the various embodiments are not limited by the acts illustrated and/or by the order of acts, for example acts can occur in various orders and/or concurrently, and with other acts not presented and described herein. Furthermore, not all illustrated acts may be required to implement the flow diagrams and/or methods in accordance with the disclosed subject matter. In addition, those skilled in the art will understand and appreciate that the methods could alternatively be represented as a series of interrelated states via a state diagram or events. Additionally, it should be further appreciated that the methods disclosed hereinafter and throughout this specification are capable of being stored on an article of manufacture to facilitate transporting and transferring such methods to computers. The term article of manufacture, as used herein, is intended to encompass a computer program accessible from any computer-readable device or computer-readable storage/communications media.

Referring now to FIG. 9, illustrated is an example method 900 that transmits cell user occupancy data, which is employed to facilitate efficient traffic steering, according to an aspect of the subject disclosure. As an example, method 900 can be implemented by one or more network devices of RAN, for example, a target access point (e.g., base station, eNB, HNB, etc.) In another example, method 900 can be implemented by one or more devices of a core mobility network (e.g., a network load management system).

At 902, cell user occupancy associated with the target access point can be determined. As an example, the cell user occupancy can represent a maximum number of devices that can be coupled to/served by the target access point at a given instant. At 904, the cell user occupancy can be normalized, for example, to an indicator value from “1” to “10”. As an example, the indicator value can comprise a composite value relative to different cell types/capacities. For example, an index number “2” can be assigned to a femtocell; an index “4” can be assigned to a picocell; an index “10” can be assigned to a macro cell; and so on. It is noted that the cell user occupancy data is not limited to the above index values, and can comprise most any normalization and/or classification technique. For example, the cell user occupancy can be classified as “low,” “regular,” “high,” etc. based on predefined threshold values.

Further, at 906, the cell user occupancy data can be transmitted to neighboring access points (e.g., access points that are within a predefined distance from the target access point, access points that have at least partially overlapping coverage areas, etc.) to facilitate traffic steering associated with UEs that are served by the neighboring access points. For example, if the cell user occupancy of the target access point is high (e.g., above a defined threshold), a probability that the target access point will not get congested and/or will be able to handle the traffic from the UE is high. Accordingly, one or more data flows associated with the UEs can be communicated via the target access point. In one aspect, the cell user occupancy data can be transmitted to the neighboring access points periodically, on demand, in response to determining a change in the occupancy data, during initialization, etc.

FIG. 10 illustrates an example method 1000 that facilitates network selection to efficiently steer traffic associated with a UE from a first RAN to a second RAN, according to an aspect of the subject disclosure. As an example, method 1000 can be implemented by a source access point (and/or UE coupled to the source access point) to determine whether a connection to a new network is to be performed. At 1002, cell user occupancy data can be received, for example, from a set of neighboring access points (e.g., target access point). As an example, the cell user occupancy data represents a maximum number of UEs that the neighboring access points are capable of simultaneously (or substantially simultaneously) supporting. At 1004, a current network load index of the neighboring access point can also be received, for example, from the neighboring access point. As an example, the cell user occupancy data and the current load index can be received in the same or different messages. At 1006, the received information can be analyzed and at 1008, one of the neighboring access points can be selected as a candidate for traffic steering based on the analysis. For example, a first neighboring access point (e.g., a macro cell) that is at 80% load and has been assigned a cell user occupancy indicator of “9” can be selected as the candidate cell over a second neighboring access point (e.g., a femtocell) that is at 70% load that has cell user occupancy indicator as “1”.

In one aspect, mobility parameters can be biased based on the current load index and the cell user occupancy of the neighboring access point. A weighting on the cell user occupancy can be dynamically and/or automatically adjusted based on the current load index and triggering thresholds. In the above example, mobility parameters associated with the first neighboring access point can be assigned a positive bias while mobility parameters associated with the second neighboring access point can be assigned a negative bias. It can be noted that various additional parameters such as (but not limited to) device preferences, application preferences, user defined policies, operator/service provider-defined policies, etc. can be employed to facilitate the traffic steering.

FIG. 11 illustrates an example method 1100 for determining whether traffic associated with a UE is to be steered from a source access point to a target access point, according to an aspect of the subject disclosure. As an example, method 1100 can be implemented by the source access point (and/or a UE coupled to the source access point device) to determine whether a handover (and/or additional connection) to a new network is to be performed. At 1102, cell user occupancy data associated with the target access point can be received. As an example, a current load index for the target access point can also be received. Further, at 1106, it can be determined whether the cell user occupancy data (and optionally the current load index) satisfies a predefined occupancy criterion (e.g., is greater than an occupancy threshold). If determined that the cell user occupancy data satisfies the predefined occupancy criterion, then, at 1106, a handover can be facilitated to steer one or more data flows associated with the UE from the source access point to the target access point. It is noted that the UE is not limited to performing a handover (e.g., disconnecting from the source access point) and can be simultaneously (or substantially simultaneously) coupled to both the source access point and the target access point. In this example scenario, the UE can determine, based on operator policy and/or application preferences, which data (e.g., a first set of IP flows) is to be communicated via the source access point and which data (e.g., a second set of IP flows) is to be communicated via the target access point. Further, if determined, at 1104, that the cell user occupancy data does not satisfy the predefined occupancy criterion (e.g., is less than or equal to the occupancy threshold), then, at 1108, the UE can continue to be coupled to and communicate via the source access point.

To provide further context for various aspects of the subject specification, FIGS. 12 and 13 illustrate, respectively, a block diagram of an example embodiment 1200 of an access point that facilitates traffic steering based on cell user occupancy data to facilitate traffic steering and a wireless communication environment 1300, with associated components for operation of efficient network selection in accordance with aspects described herein.

With respect to FIG. 12, in example embodiment 1200 comprises an access point 1202. As an example, the source access point 102 and/or the target access point 104 (and/or target access points 104 ₁-104 _(n)) disclosed herein with respect to system 100-800, can each include at least a portion of the access point 1202. In one aspect, the access point 1202 can receive and transmit signal(s) (e.g., traffic and control signals) from and to wireless devices, access terminals, wireless ports and routers, etc., through a set of antennas 1269 ₁-1269 _(N). It should be appreciated that while antennas 1269 ₁-1269 _(N) are a part of communication platform 1225, which comprises electronic components and associated circuitry that provides for processing and manipulating of received signal(s) (e.g., a packet flow) and signal(s) (e.g., a broadcast control channel) to be transmitted. In an aspect, communication platform 1225 can include a transmitter/receiver (e.g., a transceiver) 1266 that can convert signal(s) from analog format to digital format (e.g., analog-to-digital conversion) upon reception, and from digital format to analog (e.g., digital-to-analog conversion) format upon transmission. In addition, receiver/transmitter 1266 can divide a single data stream into multiple, parallel data streams, or perform the reciprocal operation. Coupled to transceiver 1266 is a multiplexer/demultiplexer 1267 that facilitates manipulation of signal in time and/or frequency space. Electronic component 1267 can multiplex information (data/traffic and control/signaling) according to various multiplexing schemes such as time division multiplexing (TDM), frequency division multiplexing (FDM), orthogonal frequency division multiplexing (OFDM), code division multiplexing (CDM), space division multiplexing (SDM), etc. In addition, mux/demux component 1267 can scramble and spread information (e.g., codes) according to substantially any code known in the art; e.g., Hadamard-Walsh codes, Baker codes, Kasami codes, polyphase codes, and so on. A modulator/demodulator 1268 is also a part of operational group 1225, and can modulate information according to multiple modulation techniques, such as frequency modulation, amplitude modulation (e.g., M-ary quadrature amplitude modulation (QAM), with M a positive integer), phase-shift keying (PSK), and the like.

Access point 1202 also includes a processor 1245 configured to confer functionality, at least partially, to substantially any electronic component in the access point 1202, in accordance with aspects of the subject disclosure. In particular, processor 1245 can facilitates implementing configuration instructions received through communication platform 1225, which can include storing data in memory 1255. In addition, processor 1245 facilitates processing data (e.g., symbols, bits, or chips, etc.) for multiplexing/demultiplexing, such as effecting direct and inverse fast Fourier transforms, selection of modulation rates, selection of data packet formats, inter-packet times, etc. Moreover, processor 1245 can manipulate antennas 1269 ₁-1269 _(N) to facilitate beamforming or selective radiation pattern formation, which can benefit specific locations covered by the access point 1202; and exploit substantially any other advantages associated with smart-antenna technology. Memory 1255 can store data structures, code instructions, system or device information like device identification codes (e.g., International Mobile Station Equipment Identity (IMEI), Mobile Station International Subscriber Directory Number (MSISDN), serial number . . . ) and specification such as multimode capabilities; code sequences for scrambling; spreading and pilot transmission, floor plan configuration, access point deployment and frequency plans; and so on. Moreover, memory 1255 can store configuration information such as schedules and policies; geographical indicator(s); network load data, cell user occupancy data (e.g., of access point 1202 and/or neighboring access points), historical logs, and so forth. In one example, data store 206 can be implemented in memory 1255.

In embodiment 1200, processor 1245 can be coupled to the memory 1255 in order to store and retrieve information necessary to operate and/or confer functionality to communication platform 1225, network interface 1235 (e.g., that coupled the access point to core network devices such as but not limited to a network controller), and other operational components (e.g., multimode chipset(s), power supply sources . . . ; not shown) that support the access point 1202. The access point 1202 can further include a occupancy determination component 208, a data transfer component 212, an AI component 802 ₁, a data reception component 302, a traffic steering component 304, a neighbor management component 306, and/or an AI component 802 ₂ which can include functionality, as more fully described herein, for example, with regard to systems 100-400 and 800. In addition, it is to be noted that the various aspects disclosed in the subject specification can also be implemented through (i) program modules stored in a computer-readable storage medium or memory (e.g., memory 1255) and executed by a processor (e.g., processor 1245), or (ii) other combination(s) of hardware and software, or hardware and firmware.

Referring now to FIG. 13, there illustrated is a wireless communication environment 1300 that includes two wireless network platforms: (i) A first network platform 1310 (e.g., macro network platform) that serves, or facilitates communication with user equipment 1375 via a first RAN 1370. As an example, in cellular wireless technologies (e.g., 3GPP UMTS, HSPA, 3GPP LTE, 3GPP UMB, 4G LTE, etc.), the first network platform 1310 can be embodied in a Core Network; and (ii) A second network platform 1380 (e.g., macro network platform, femto network platform, wireless local area network (WLAN) platform, etc.), which can provide communication with UE 1375 through a second RAN 1390 linked to the second network platform 1380. It should be appreciated that the second network platform 1380 can offload UE 1375 from the first network platform 1310, once UE 1375 attaches (e.g., based on the traffic steering described herein) to the second RAN. In one example, the first RAN and the second RAN can be commonly operated and/or deployed by a common service provider.

It is noted that RAN (1370 and/or 1390) includes base station(s), or access point(s), and its associated electronic circuitry and deployment site(s), in addition to a wireless radio link operated in accordance with the base station(s). Accordingly, the first RAN 1370 can comprise various access points like source access point 102, while the second RAN 1390 can comprise multiple access points like target access point 104.

Both the first and the second network platforms 1310 and 1380 can include components, e.g., nodes, gateways, interfaces, servers, or platforms, that facilitate packet-switched (PS) and/or circuit-switched (CS) traffic (e.g., voice and data) and control generation for networked wireless communication. For example, the first network platform 1310 includes CS gateway node(s) 1312 which can interface CS traffic received from legacy networks like telephony network(s) 1340 (e.g., public switched telephone network (PSTN), or public land mobile network (PLMN)) or a SS7 network 1360. Moreover, CS gateway node(s) 1312 interfaces CS-based traffic and signaling and gateway node(s) 1318. In addition to receiving and processing CS-switched traffic and signaling, gateway node(s) 1318 can authorize and authenticate PS-based data sessions with served (e.g., through the first RAN 1370) wireless devices. Data sessions can include traffic exchange with networks external to the first network platform 1310, like wide area network(s) (WANs) 1350; it should be appreciated that local area network(s) (LANs) can also be interfaced with first network platform 1310 through gateway node(s) 1318. Gateway node(s) 1318 generates packet data contexts when a data session is established. It should be further appreciated that the packetized communication can include multiple flows that can be generated through server(s) 1314. The first network platform 1310 also includes serving node(s) 1316 that conveys the various packetized flows of information or data streams, received through gateway node(s) 1318. It is to be noted that server(s) 1314 can include one or more processors configured to confer at least in part the functionality of first network platform 1310. To that end, one or more processors can execute code instructions stored in memory 1330 or other computer-readable medium, for example.

In example wireless environment 1300, memory 1330 can store information related to operation of first network platform 1310. Information can include business data associated with subscribers; market plans and strategies, e.g., promotional campaigns, business partnerships; operational data for mobile devices served through first network platform; service and privacy policies; end-user service logs for law enforcement; and so forth. Memory 1330 can also store information from at least one of telephony network(s) 1340, WAN(s) 1350, or SS7 network 1360. Many different types of information can be stored in memory 1330 without departing from example embodiments.

Gateway node(s) 1384 can have substantially the same functionality as PS gateway node(s) 1318. Additionally or optionally, the gateway node(s) 1384 can also include substantially all functionality of serving node(s) 1316. In an aspect, the gateway node(s) 1384 can facilitate handover resolution, e.g., assessment and execution. Server(s) 1382 have substantially the same functionality as described in connection with server(s) 1314 and can include one or more processors configured to confer at least in part the functionality of the first network platform 1310. In one example, the network load management system 402 can be implemented or executed by server(s) 1382 and/or server(s) 1314. To that end, the one or more processor can execute code instructions stored in memory 1386, for example.

Memory 1386 can include information relevant to operation of the various components of the second network platform 1380. For example operational information that can be stored in memory 1386 can comprise, but is not limited to, subscriber information; contracted services; maintenance and service records; cell configuration (e.g., devices served through second RAN 1390; access control lists, or white lists); service policies and specifications; privacy policies; add-on features; and so forth.

Referring now to FIG. 14, there is illustrated a block diagram of a computer 1402 operable to execute the disclosed communication architecture. In order to provide additional context for various aspects of the disclosed subject matter, FIG. 14 and the following discussion are intended to provide a brief, general description of a suitable computing environment 1400 in which the various aspects of the specification can be implemented. While the specification has been described above in the general context of computer-executable instructions that can run on one or more computers, those skilled in the art will recognize that the specification also can be implemented in combination with other program modules and/or as a combination of hardware and software.

Generally, program modules include routines, programs, components, data structures, etc., that perform particular tasks or implement particular abstract data types. Moreover, those skilled in the art will appreciate that the inventive methods can be practiced with other computer system configurations, including single-processor or multiprocessor computer systems, minicomputers, mainframe computers, as well as personal computers, hand-held computing devices, microprocessor-based or programmable consumer electronics, and the like, each of which can be operatively coupled to one or more associated devices.

The illustrated aspects of the specification can also be practiced in distributed computing environments where certain tasks are performed by remote processing devices that are linked through a communications network. In a distributed computing environment, program modules can be located in both local and remote memory storage devices.

Computing devices typically include a variety of media, which can include computer-readable storage media and/or communications media, which two terms are used herein differently from one another as follows. Computer-readable storage media can be any available storage media that can be accessed by the computer and includes both volatile and nonvolatile media, removable and non-removable media. By way of example, and not limitation, computer-readable storage media can be implemented in connection with any method or technology for storage of information such as computer-readable instructions, program modules, structured data, or unstructured data. Computer-readable storage media can include, but are not limited to, RAM, ROM, EEPROM, flash memory or other memory technology, CD-ROM, digital versatile disk (DVD) or other optical disk storage, magnetic cassettes, magnetic tape, magnetic disk storage or other magnetic storage devices, or other tangible and/or non-transitory media which can be used to store desired information. Computer-readable storage media can be accessed by one or more local or remote computing devices, e.g., via access requests, queries or other data retrieval protocols, for a variety of operations with respect to the information stored by the medium.

Communications media typically embody computer-readable instructions, data structures, program modules or other structured or unstructured data in a data signal such as a modulated data signal, e.g., a carrier wave or other transport mechanism, and includes any information delivery or transport media. The term “modulated data signal” or signals refers to a signal that has one or more of its characteristics set or changed in such a manner as to encode information in one or more signals. By way of example, and not limitation, communication media include wired media, such as a wired network or direct-wired connection, and wireless media such as acoustic, RF, infrared and other wireless media.

With reference again to FIG. 14, the example environment 1400 for implementing various aspects of the specification includes a computer 1402, the computer 1402 including a processing unit 1404, a system memory 1406 and a system bus 1408. As an example, the component(s), server(s), equipment, system(s), and/or device(s) (e.g., source access point 102, target access point 104, target access points 104 ₁-104 _(n), UE 108, network configuration server 202, occupancy determination component 208, data transfer component 212, data reception component 302, traffic steering component 304, neighbor management component 306, network load management system 402, MME 602, SGSN 604, RNC 606, AI components 802 ₁-802 ₂, access point 1202, first network platform 1310, second network platform 1380, etc.) disclosed herein with respect to system 100-800 and 1200-1300 can each include at least a portion of the computer 1402. The system bus 1408 couples system components including, but not limited to, the system memory 1406 to the processing unit 1404. The processing unit 1404 can be any of various commercially available processors. Dual microprocessors and other multi-processor architectures can also be employed as the processing unit 1404.

The system bus 1408 can be any of several types of bus structure that can further interconnect to a memory bus (with or without a memory controller), a peripheral bus, and a local bus using any of a variety of commercially available bus architectures. The system memory 1406 includes read-only memory (ROM) 1410 and random access memory (RAM) 1412. A basic input/output system (BIOS) is stored in a non-volatile memory 1410 such as ROM, EPROM, EEPROM, which BIOS contains the basic routines that help to transfer information between elements within the computer 1402, such as during startup. The RAM 1412 can also include a high-speed RAM such as static RAM for caching data.

The logical connections depicted include wired/wireless connectivity to a local area network (LAN) 1452 and/or larger networks, e.g., a wide area network (WAN) 1454. Such LAN and WAN networking environments are commonplace in offices and companies, and facilitate enterprise-wide computer networks, such as intranets, all of which can connect to a global communications network, e.g., the Internet.

When used in a LAN networking environment, the computer 1402 is connected to the local network 1452 through a wired and/or wireless communication network interface or adapter 1456. The adapter 1456 can facilitate wired or wireless communication to the LAN 1452, which can also include a wireless access point disposed thereon for communicating with the wireless adapter 1456.

When used in a WAN networking environment, the computer 1402 can include a modem 1458, or is connected to a communications server on the WAN 1454, or has other means for establishing communications over the WAN 1454, such as by way of the Internet. The modem 1458, which can be internal or external and a wired or wireless device, is connected to the system bus 1408 via the serial port interface 1442. In a networked environment, program modules depicted relative to the computer 1402, or portions thereof, can be stored in the remote memory/storage device 1450. It will be appreciated that the network connections shown are example and other means of establishing a communications link between the computers can be used.

The computer 1402 is operable to communicate with any wireless devices or entities operatively disposed in wireless communication, e.g., desktop and/or portable computer, server, communications satellite, etc. This includes at least WiFi and Bluetooth™ wireless technologies. Thus, the communication can be a predefined structure as with a conventional network or simply an ad hoc communication between at least two devices.

WiFi, or Wireless Fidelity, allows connection to the Internet from a couch at home, a bed in a hotel room, or a conference room at work, without wires. WiFi is a wireless technology similar to that used in a cell phone that enables such devices, e.g., computers, to send and receive data indoors and out; anywhere within the range of a base station. WiFi networks use radio technologies called IEEE 802.11 (a, b, g, n, etc.) to provide secure, reliable, fast wireless connectivity. A WiFi network can be used to connect computers to each other, to the Internet, and to wired networks (which use IEEE 802.3 or Ethernet). WiFi networks operate in the unlicensed 5 GHz radio band at an 54 Mbps (802.11a) data rate, and/or a 2.4 GHz radio band at an 11 Mbps (802.11b), an 54 Mbps (802.11g) data rate, or up to an 600 Mbps (802.11n) data rate for example, or with products that contain both bands (dual band), so the networks can provide real-world performance similar to the basic 10BaseT wired Ethernet networks used in many offices.
